Mice lacking the helicase domain fo the WRN ortholog exhibit many phenotypic features of Werner Syndrom, including a pro-oxidant status and a shorter mean lifespan. Mice with a deletion in the helicase domain [9789047] recapitulates most of the Werner syndrome phenotypes, including an abnormal hyaluronic acid excretion, higher reactive oxygen species levels, dyslipidemia, increased genomic instability, and cancer incidence. Wrn(Dehl/Dehl) mutant mice have a 10 - 15% decrease in their mean lifespan [12707040; 19741171].
Mean: -10 to -15
